This invention relates to work-jogging attachments for sewing machines, and more particularly to a new and improved bight regulating means therefor.

Work-jogging attachments of the type to which this invention is applicable, comprise generally devices for holding and presenting the work to the needle, together with mechanism for moving or jogging the wont-holding devices to effect a v patern of stitcl'ies. Whether the resulting stitch pattern be a closed one, as in the case of a but-' tonhole, or a continuous one as in hemstitching, the term bight is used herein to designate stitchy-stitch work movement laterally of the general progress of the work. Thus in a button hole, the amplitude of the zigzag stitches along each side represents the *bightfl Work-jogging attachments are primarily used with family type sewingmachines, in which use the attribute of versatility ranks high in importance'. An object of the present invention is to provide a bight regulating structure for a workjogging attachment which not only encompasses the usual range of bight sizes but also includes a position in which no bight' occurs, in which l beltion a straight tack of stitches may be formed. Thus, by means of the instant invention, theusefulness and. versatility of awork-jogging attachment will be enhanced, since in addition to the normal purpos for which the attachment is designed, straight tacks may be produced having the appearance as'fif made by an organized tacking machine. Such tacks are useful, for instance, to attach straps, to reenforce the corners of pocket openings and the like,

In addition, it is an object of this invention to provide a mechanism whereby the lateral p sition of the work holding devices may Joe-accurate- 1y controlled so that two or more parallel tacks may be produced. This feature, "when applied to a 'buttonhole atachment, provides an attachment which is especially well suited ior-the'i-n-itial stitching operations involved the preparation Of hound huttor'iholes, iby a'usual method which willjlae described sieta lhercinafi r- .In the accompanyingdrawings, a preferred embodiment .of the invention is minimised connectilon with a buttonhole ttachment of h type discloses the N. .Ailmquist BatenrN 2,i.821,.6.07, .Sepiembcr 20', 19491.

The buttonhole attachment with which the novel high-t regulating means is associated in the preferred embodiment isillust-rated in Figs. 1 and 2 in operative position on a sewing machine. The sewing machine, which isillustrated fragmentarily in the drawings, is of usual construction including a work-supporting plate Ill and a bracket-arm (not shown) which overhangs the Work-supporting plate. Sl-ldably journaled in the bracket-armis a vertically reciprocating needlebar l-l provided at its free extremity with a needle-clamping screw I2 by which a needle l4 may be secured thereto. Also journaled in the bracket-arm is a presser-bar t5, the free end of which is drilled and tapped to accommodate a thumb screw it which serves in ordinary stitch ing operations to secure a presser-foot to the presser' bar.

The illustrated buttonhole attachment, similar to that disclosed in the above mentioned Almquist patent, is supported by the presser-bar and utilizes the reciprocatory motion of the needlebar to efiect work-shifting movement. To this end, the attachment is provided with a frame including a fiat horizontal base-plate 20, a U- shaped pattern-cam supporting bracket 2 l and a block 22 in which is formed a presser-bar accommodating seat 23 and a clearance aperture for the thumb screw l6 by which the attachment frame may be securely fastened to the presserbar.

The attachment is provided with a work-engaging presser-foot 25 formed with an elongated opening 25 within which the buttonhole pattern of stitches is formed. The presser-foot is pivotally supported on the forward extremity of a flat, substantially horizontal, shank 27 which is disposed to underlie the base-plate 28 of the attachment frame, as is illustrated clearly in Figs. 3, 4 and 5.

With the button hole attachment which is 11- lustrated in the drawings, there is provided an actuating mechanism which is carried by the attachment frame and which is driven by the vertically reciprocatory movements of the needle-.

bar so as to impart movement to the work-engaging presser-loot. Since the usual feed mechanism or the sewing machine is not used and, in fact, may be detrimental to proper work-shifting by the button hole attachment, a feed cover plate 3i; is secured in position between the work-supporting plate Hi and the attachment presser-foot 25.

The actuating mechanism of the attachment does not shift the presser-foot directly, but rather it is arranged to impart movement to the presser shank 2'! at a point spaced from the presser-foot 25. A connection is provided between the attachmerit frame and the presser-foot shank by which movements of the presser-foot may be controlled. This invention is primarily concerned with the control connection, however, the actuating mechanism now will be described in sufficient detail to enable a person skilled in the art to comprehend the invention. 7

An actuating lever 23 is freely journaled on a studshaft 29 disposed between the upstanding arms of the attachment frame bracket 2i. The lever 28 at its free end is bifurcated and arranged to engage the needle clamp screw I2 so that an oscillatory movement is imparted to the lever by the reciprocatory' needle-bar. By means of a ratchet 3i and a pawl 32, the oscillatory movement of the actuating lever imparts step-by-step turning movement to the stud-shaft and to a bar rel pattern-cam 33 secured thereto.

Carried by a vertical pivot-pin 34, which is secured to the frame-base substantially on the longitudinal center-line a:-:n thereof, is a horizontally swinging lever 35. The lever 35 carries at its forward extremity a roller-follower 35 which enters and tracks the groove of the barrel pattern-cam. The opposite extremity of the lever 35 is provided with abridge portion 37 which is spaced above the lever 35 and, together with the lever, rotatably supports a hub portion 40 of a ratchet wheel 43 on a vertical axis. At the lower extremity of the ratchet-wheel hub 40 beneath the lever 35, a pinion 35 is fixed coaxially with the ratchet wheel 45 and adapted to mesh with a closed elongated pattern rack 4! which is replaceably secured in the shank 21 and maintained in position by the pivoted bottom plate 42 of the attachment frame.

The ratchet wheel 43 engages a spring pawl 44 which is carried by the frame, whereby the side-to-side movements of the lever 35 which are imparted by thepattern barrel cam 33, cause step-by-step turning movements of the pinion 39.

Y Thus by meansof the operative engagement between the pinion 39 of the actuating mechanism and the pattern rack 4! of the presser-foot shank, the side-to-side movements of the lever 35 impart to the presser-foot shank similar stitch-by-stitch lateral movements perpendicular to a longitudinal axis of the frame indicated by line :cx, Fig. 2, while the ratchet-controlled turning movements of the pinion shaft cause the pinion to track the pattern rack, thus imparting longitudinal movements to the presser-foot shank.

In order-that the lateral movements of the presser-foot may be controlled, an adjustable connection is provided between the attachment frame and the presser-foot shank by means of which a pivotal axis is determined for turning movements of the presser shank in response to lateral movements of the pattern rack.

The connection is designed to provide for a wide range of adjustment of the position of the shank pivotal axis including a position in which the pivotal axis corresponds with the axis of needle reciprocation, in which position it will be understood, the attachment will produce a stitch pattern having no bight, i. e., a straight tack having in-line stitches.

To this end, the presser-shank is formed with an outwardly protruding portion 48 formed with a slot 49 which defines opposed-guiding surfaces and 5! disposed parallel to the length of the pattern rack and which protrude forwardly to a point opposite the forward portion of the presser-foot opening 26. overlying the extended portion 48 of the presser-shank is a lateral extension 52 of the attachment frame base 20. The frame base extension is provided with a slot 53 which is disposed substantially parallel to the longitudinal center-line 03-1: of the frame base and which extends forwardly to a point opposite the needle ax1s.

A block 54 is slidably confined between the guiding surfaces 59 and 5| in the presser-shank. The slide-block is formed at its lower end with an enlarged head portion 55, Fig. 1, and at its upper extremity with a reduced threaded portion 56 which extends upwardly through the slot 53 in the frame base extension. The threaded portion accommodates a thumb nut 57, by which the slide-block may beadjustably clamped in any desired position along the slot 53, and since the slide-block is of a greater thickness than the lateral extension 48 of the presser-shank, the shank is always slidably pivoted to the frame base by the slide-block.

In the drawings, Fig. 3 illustrates the relationship of parts when the slide-block is positioned in the rearward portion of the slot 53, resulting in a stitch pattern 60 having a substantially wide bight. Fig. 4 illustrates the straight tack stitch pattern 6| produced when the slide-block is adjusted to its extreme forward position in which no bight is produced. These figures also show that the slide-block does not in itself form the pivotal axis for the presser-shank, but rather that the slide-block together with the actuating mechanism determine a pivotal axis A which always .occurs substantially along the longitudinal centerline a:a: of the attachment frame and at a point opposite the position of the slideblock. Thus, in the position of bight adjustment illustrated in Fig. 3, the pivotal axis for the shank 21 is disposed on the longitudinal frame centerline indicated by the line :ra: and part way between the pinion .39 and the needle 14' so that for each lateral movement imparted 5. to the shank by the pinion 39 a lateral movement in the opposite direction is imparted to the presser-foot, the proportion, of course, depending on the position of the slide-block 54 and the corresponding position of the axis of shank turning movement A. As illustrated in Fig. 4, the slide-block is positioned opposite the needle axis so that the axis of turning movements of the shank carers-ponds with the needle axis and no bight results.

As illustrated in Fig. 5, an additional feature of the present invention is the provision of a transverse slot 58 which intersects the forward extremity of the longitudinal slot 53 in the frame base20. In the preferred embodiment, the transverse slot 58 is disposed on an are shown by the dashed line 11-4 of Fig. 5, the center of curveture of the arc coincides substantially with the point of engagement between the pinion 39 of the actuating mechanism and the pattern rack 4| of the presser-foot shank. By this construetion, when the slide-block 54 is in extreme forward position of adjustment in which a straight tack is formed, the shank 21 may be shifted laterally so as to shift the position of the work and consequently the position of the straight tack bodily in a lateral direction. Since the slot 58 is disposed on an are about the point of contact between the actuating mechanism and the pressershank as its center, the shank 21, when shifted from one lateral position to another, causes parallel straight tacks of equal length to be made With each of the tacks terminating on .a common right line.

The specification thus far has dealt primarily with a description of the structural provisions of the preferred embodiment. The manner in which the above described arrangement of parts operates to locate the axis of turning movement of the 'presser-shank at the axis of the needle to produce a straight line of stitches will now be described.

As shown in Fig. 8, the motion transmitted to the presser-foot shank by the pinion- 39 may be resolved into twocomponents, one component D in a direction parallel to. the longitudinal axis .r-zc of the attachment frame, 1. e., toward and away from the needle by virtue of the tracking of the length of the pattern rack by the pinion, and another component B laterally of the attachment axis a: a due to oscillation of the pinion 39and also due to tracking of the pinion about. the ends of the pattern rack. Since the slot 49, as stated above, is'parallel to the length of the pattern rack and consequently is parallel to the direction of the longitudinal component D, this component results in translatory movement of the presser-foot shank.

The lateral movements imparted to the shank by the pinion 39, since they are relatively small in comparison with the length of the attachment, occur in a direction B substantially perpendicular to the axis of the attachment frame. In response to lateral movement 13 of the driving connection, the presser-foot shank is constrained at the control connection between block 54 and slot d9 to move in the direction of the slot, i. e., substantially parallel to the longitudinalaxis of the frame as indicated by the arrow C in Fig. 8. Iii-accordance with kinematic principles, when the direction of motion of two points on a member are known, the axis of turning movement of the member is located atthe intersection of two lines each passing through one of the points-and disposed" perpendicularto the direction of motion or that respective point. In Fig. 8 such a per pendicular through the point of engagement of the pinion 39 and the rack 41 substantially coincides with the'frame axis :c-r while the line it represents such a line drawn through the control connection. When the block 511 is clamped at the forward extremity of the slot :33 in the attachment frame as is shown in Fig. 8, the line d intersects the axis a:-:r of the attachment at a point A substantially coincident with the axis of the needle [4, and, therefore, the presser-rfoot shank pivots'about the axis of the needle and only the translatory motion or the presser-shank is reflected in the resulting straight line of stitches produced.

As stated previously in the specification, provision is made for shifting the slide-block 54 with respect to the attachment frame in a direction transversely of the slot 49 in the presser-foot shank 21. Since the shank embraces the slideblock 54, the shank, the presser-foot, and any work gripped thereby is likewise shifted with respect to the needle as illustrated in dotted lines in Fig. 8, thus making it possible to produce spaced groups of stitchessince the pinion 39 and the actuating mechanism are not shifted with the presser-shank, the direction or components D and B of motion imparted to the presser-shank in the shifted position remain unchanged and the line perpendicular to the lateral motion and through the point of-engagement of the pinion 39 and the rack Ail remains substantially coincident with the frame axis :c--x. The direction of motion between the block M and slot 19, however, changes. considerably as indicated by C. The block 54, therefore, when it is shifted in a direction transversely of the slot 19 must also be shifted along the slot 49 so that in the new position the line d through the block and perpendicular to the slot 49 will intersect the axis of the needle I l and the frame axis 02-:1: as before. The

path on the frame extension 52 along which the block 5! must be shifted to maintain this relation of parts is an arc y--y having its center of curvature substantially at the point of engagement of the pinion 39 and the pattern rack 4|. Since in the preferred embodiment the radius of curvature of the arc yy is large, it will be appreciated that the path could be ma'de straight and tangent to the are without introducing appreciable error within the. limits of the relatively small seam spacing adjustments required.

Referring again to Fig. 5 of the preferred em bodiment, the lateral spacing between successive tacks may be effected by loosening the thumb nut 51 so that the slide-block 5d, the threaded stud 5b and the thumb nut 51 are released from clamped relation with the frame base extension 52. The transverse slot 58 in the frame base extension 52 is formed to provide clearance for the stud 56 so that when the thumb nut 5 is loosened, the presser-foot shank 2Tmay be shifted laterally carrying with it the presser-foot 25 and the stud 56 which shifts along the slot 58. Consequently, the maximum lateral spacing between any twoparallel lines of stitches thus formed is limited by the length of the lateral slot 58. Fig. '5 illustrates an arrangement of parts in which stud :56 is positioned at one extremity of the slot 58 in which positionithe line of stitches '13 will be produced. Also illustrated in Fig. 5 is a line of stitches 12 which corresponds to that which will be produced should the parts be shifted to'a positi -on in which the stud 56' is disposed at the opposite extremity'otthe slot 58. The illustrated lines of stitches 12 and I3, therefore, represent the maximum lateral spacing which may be obtained with the illustrated construction. Since by means of the thumb nut 51 the parts may be clamped together with the stud 56 disposed at any selected point along the transverse slot 58, it is possible within limits to obtain any desired lateral spacing of the lines of stitches by simply loosening the thumb nut 59 after one line of stitches has been formed, shifting the presser-foot the desired lateral amount, and tightening the thumb nut. Further operation of the attachment will produce the second line of stitches at the desired spacing. It will be apparent that the scope of the instant invention is sufficiently broad to encompass not only the specific thumb nut clamp device of the preferred embodiment but also any equivalent clamp means for selectively securing the slide-block 54 to the frame 20 along the path y1 This arrangement of parallel tacks is particularly advantageous in the production of bound buttonholes by the usual method in which, as illustrated in Figs. 6 and '7, a patch of piping fabric 10 is first secured to a body fabric H by parallel lines of stitches l2 and 13. The fabrics are then slashed between the lines of stitches, as indicated by dot and dash lines in Fig. 6. The patch is pushed through the slot and folded so as to be visible through the resulting opening as illustrated in Fig. 7. With this method, the first step, that of securing the patch to the body fabric, is of primary importance as to the appearance, location, and the strength of the resulting buttonhole. Should the lines of stitches be wavy or of different lengths, or offset one from the other longitudinally, the defect will be readily apparent in the finished product. The instant invention as applied to a buttonhole attachment provides a means for producing parallel straight tacks which are flawlessly accurate, and by which consistently square and straight sided bound buttonholes, identical in size one with another may be produced.
